Path loss determination method and apparatus

Abstract

A method for determining pass path can be applied to a narrowband internet of things (NB-IoT) device. The method includes: determining transmission power of a downlink narrowband reference signal (NRS); determining a measurement value of narrowband reference signal received power (NRSRP); and in a case that a preset higher layer filter parameter is not received from a base station, determining path loss between the base station and the UE according to the transmission power of the downlink NRS and the measurement value of the NRSRP. As such, during the determination of transmission power of the NB-IoT device, a configuration information sending burden of the base station can be reduced, unnecessary retransmission can be avoided, and power consumption of user equipment (UE) in the NB-IoT may be reduced.
